Step-by-Step Design
1. Determine desired board spacing (0.50 mm increments)
2. Select Dubox™ receptacle and calculate stack height
Stack Height = Board Spacing– Receptacle Height
3. Find the insertion depth from the chart below.
Calculate max./min. OAL
OAL = Stack Height + solder side + Insertion Depth
4. Select the Pin Style with OAL between max.
and min. values
Example:
1. Application requires a board spacing of 22.50
2. Select the Dubox™ Low Profile Receptacle
with height of 7.00
The Header Stack Height is 22.50 - 7.00 = 15.50
3. For standard board applications, the
3.05 solder side is selected
OAL (max.)= 15.50 + 3.05 + 6.10 = 24.65
OAL (min.) = 15.50 + 3.05 + 3.86 = 22.41
4. Select Pin Style 08 with OAL = 23.50
5. Part Number is 54122-108-72-1550
